What is the importance of Gmail’s two-step verification?
As you know, stealing email passwords is very easy for hackers. Factors such as using the same passwords for more than one website, downloading software from the Internet, clicking on links in unknown emails, and so on can all put your passwords at risk.
For example, if someone gains access to your Gmail account, they can:
- Read and delete all your emails.
- Send unwanted emails to your contacts by impersonating them.
- Use your email to access passwords, bank accounts, etc.
- All of these can put your important information at risk.
For example, when a user goes to the Fa hosting site and buys hosting, their hosting account information is immediately sent to them via email after payment. The user launches their website with peace of mind, unaware that their hosting account information is still in their email list. At this point, if a hacker enters your email, they can easily extract and use important information.
What is a Google verification code?
By using two-factor authentication for Gmail, you can prevent unauthorized access to your Gmail account. Even if someone gains access to your email address and password, they cannot access your email account as long as they do not have access to your phone number.
If you activate two-factor authentication for your Gmail account, the way you log in will be different! In addition to entering a password, you will be asked for additional information to verify your identity. Only if you can successfully pass through the second layer of security created on your email account can you access your Gmail account. You can take action in the following three ways:
- Verification via phone number through text message or voice call
- Google identity verification application for sending verification code
- A second alternative, such as a security key or backup code
In identity verification through a phone number, a security code is assigned to you via text message or a voice call from Google. By entering the received code in the desired field and confirming it, your identity will be verified, and you can access your Gmail account. Additionally, an application has been developed by Google that will send security codes to you, eliminating the need for text message or voice call verification with your phone number.
It’s interesting to know that you can use a security key for identity verification, in which case you will need a flash drive containing the key file and a USB port.
All of these aspects will be further explained in more detail below. By enabling two-step verification on your Gmail account, you create two layers of security. The first layer is your password, and the second layer is one of the security measures (security code, security key, etc.). The only way to access your emails is by passing through the second layer.
In simple terms, it can be said that accessing your account is only possible through what you know (your password) and what you have (security key or your mobile number).

Disabling Gmail’s 2-step verification
The steps to disable 2-Step Verification are as follows:
- Go to myaccount.google.com to log in to your Gmail account.
- Enter your Gmail email address and password.
- Click Sign in. (If you haven’t set up your system as a trusted computer, you’ll need to go through 2-step verification steps.)
- You will then enter your Gmail account settings.
- In the Security section, click 2-Step Verification.
- Click Turn off according to the image.
Forgetting your Gmail password
Each of the above cases is listed in the Gmail Authentication and Security Actions list and can be used to log in. For example, in the image below, three items have been defined as authentication and backup codes. So if I forget my password, I can recover my Gmail with one of these three methods.
For this case, when you log in to your Gmail, click on the Forgot Password option. Like the image below, click on Try another way each time until you reach the point where you can recover your Gmail through it. If you have 8-digit digital codes, when you get to Enter one of 8-digit backup code, enter one of the unused 8-digit codes in the field. Otherwise, use other methods such as recovery email or phone number that you previously entered.
Finally, we recommend using this feature to improve security and prevent hacking and compromising your information. Gmail’s 2-step verification will prevent unauthorized access to your account. In this article, we tried to explain all relevant settings as well as how to enable and disable Google’s 2-step verification.
By following any of the above methods, you can easily enable Gmail’s two-factor authentication process. Both methods are reliable and easy to work with. It should be noted that using the Google Authenticator app is a better choice for people who use multiple apps and websites with two-factor authentication because this app can become a central hub for logging into all online profiles and accounts.
Google Prompt offers faster and more secure access, but it only makes sense when you need to log into your account multiple times during the week. In fact, choosing the best two-factor authentication application depends on your personal needs. Some of the best password management apps, such as Password1 and LastPass, also offer two-factor authentication services.
Also, if you are a member of social networks, you can take action right now to increase their security and enable two-factor authentication for Twitter, two-factor authentication for Instagram, two-factor authentication for Telegram, and two-factor authentication for Apple ID.
Why am I not receiving the verification code for Google authentication?
As we mentioned above, you can use the methods described to solve this problem.
Why can’t I access my Gmail account after entering the code?
This may be because the time in your Google Authenticator app is not set correctly. To fix this problem, it’s best to adjust the clock and date on your system. You can read the article “How to Set Windows Clock” for this.
Who needs two-factor authentication more?
Anyone who feels they have information on their Gmail or Google account that they don’t want hackers and unauthorized individuals to access should consider enabling two-factor authentication. Generally, regular users can choose not to enable this feature, but those with high-ranking jobs and are part of an organization’s personnel should definitely activate Gmail’s two-factor authentication service.
Is it possible to log in to Gmail without two-factor authentication?
Google has the strongest active servers in the world, so even thinking about bypassing Gmail’s two-factor authentication or hacking it is somewhat unreasonable. However, if you forget your second password for any reason, you can contact Google support via another account and share your issue with them.
